Bangkok is the capital and most populous city of Thailand. It is known in Thai as Krung Thep Maha Nakhon or simply Krung Thep. The city occupies 1,568.7 square kilometers in the Chao Phraya River delta in central Thailand and has a population of over eight million, 12.6 percent of the country's population. Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew and became the site of two capital cities: Thonburi in 1768 and Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam, later renamed Thailand, during the late-19th century, as the country faced pressures from the West. The city was at the center of Thailand's political struggles throughout the 20th century, as the country abolished absolute monarchy, adopted constitutional rule, and underwent numerous coups and several uprisings. The city grew rapidly during the 1960s through the 1980s and now exerts a significant impact on Thailand's politics, economy, education, media and modern society.

The Bridge on the River Kwai is a 1957 British-American CinemaScope and Technicolor adventure epic war film directed by David Lean and based on the 1952 novel written by Pierre Boulle.

The Burma Railway, also known as the Death Railway, the Siam–Burma Railway, the Thai–Burma Railway and similar names, is a 415-kilometre (258 mi) railway between Ban Pong, Thailand and Thanbyuzayat, Burma, built by the Empire of Japan from 1940–1944 to supply troops and weapons in the Burma campaign of World War II. This railway completed the rail link between Bangkok, Thailand and Rangoon, Burma. The name used by the Japanese Government is Thai–Men-Rensetsu-Tetsudou, which means Thailand-Burma-Link-Railway.

Hellfire Pass is the name of a railway cutting on the former Burma Railway ("Death Railway") in Thailand which was built with forced labour during the Second World War, in part by Allied prisoners of war. The pass is noted for the harsh conditions and heavy loss of life suffered by its labourers during construction. Hellfire Pass is so called because the sight of emaciated prisoners labouring at night by torchlight was said to resemble a scene from Hell.

Kwai River (The Khwae Yai River), also known as the Si Sawat, is a river in western Thailand. It has its source in the Tenasserim Hills and flows for about 380 kilometers through Sangkhla Buri, Si Sawat, and Mueang Districts of Kanchanaburi Province, where it merges with the Khwae Noi to form the Mae Klong River at Pak Phraek. In 1980, the Srinagarind Dam on the Khwae Yai was completed in Si Sawat District of Kanchanaburi Province. It is an embankment dam for river regulation and hydroelectric power generation.
